We are taking a look at the top 60 players in the San Francisco 49ers' program and will rank them from 1-60. We are going to take a look in a 12-part series, moving upward. The ranking considerations are based on 2013 production, future projections, age, and contract status:56. Guard Ryan Seymour: The former Seattle practice-squader finished the season on the 49ers' 53-man roster. He should get a long look in training camp. Because the 49ers would like to develop some young offensive linemen and because Seymour is versatile, he has a chance to stick around.
